PatentedJune 17, 1930 HEDLEY FALLA AND FRED BEBGAMI, OF MILFO CAN OPENER Application fiIed March 25, 1927.

This invention relates to can openers and it is an improvement on the. invention forming the subject matter of Patent No. 1,6341 493, granted to the joint inventor Hedley Falla of the present invention.

The general object of the invention is to provide an improved can opener which in cludes means to prevent the knife of the opener from casually jumping out of a can during the operation of the opener and also to cause the knife of the opener to slide forward on its upstroke, with the result the present construction can be operated with extreme case and will perform its functions in an efficient and expeditious manner withv very little effort on the part of the operator. 7

This invention also consists inv certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim. I

In describing our invention in detail, refcrence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is a perspective view of one form of the present invention.

Figure 2 is a View of the construction as shown in Figure 1 with the blade in a downwardly applied position in a can.

Figure 3 is a similarview of the opener as shown in Figure 2 with, the blade in an upwardly applied position.

Figure 4 is a perspective blade and shank therefor.

Figure 5 is a sectional view taken on line 5-5 of Figure 4;.

Referring to the drawings in detail and view of the knife 7 particularly to Figures 1 to 5 inclusive, the

reference numeral 1 indicates the blade of the can opener as shown in these figures and which is formed with a body 2 and said body is curved intermediate its ends in a manner to dispose the ends substantially at right angles with respect to each other as best shown in Figure 4 of. the drawings.

A shank 3 is formed with the body 2 and is adapted toreceive construction.

" Pivotally secured an, new rmiursninn Serial no. 178,341.

a handled of the usual to the body 2 adjacent its juncture with the blade 1 is a yoke 5 of substantially U-shap e configuration and includes an arm 6 disposed upon the inner side of the blade while the arm 7 thereof is bent rearwardly upon itself as at Sand is fixed in said position through the instrumental ty of the pivot pin 9wh1ch secures the yoke to the blade as above set forth. with and depending tion 10 is a guide member Formed integral from the curved por- 11 which co-operates with a reduced portion formedwitl and depending and these guides are the outer surface of is indicated by the and 3.

It Will be noted th from a guide member 11,

adapted to contact with the wall of a can which letter A in Figures 2 at the construction thus fardescribed is substantially the same as the prior invention the exception that t above identified, with he body portion 2 presents an improvement as well as the curved portion 10 of the arm 7. The blade 1 is beveled in'the usual manner to provide a cutting edge, and it cutting edge ad will be noted that the acent its outer end is provided with a notch 12, butsaid cutting edge terminates in a point 13 as clearly shown in the drawing.

The blade is further formed with a recess 14 disposed adjacent its juncture with the body portion 2, and the purpose of this recess 1a which as shown is concaved in configuration, is to provide for easy forward sliding in Figure 2 of the drawstroke as suggested ing while the notch of the blade on its up- 12 in the cutting edge of the blade is to prevent the latter from 'umnin out of the l L b clearly shown in Figure 3 of canon its upstroke as the drawing,

as it will be noted that this notched end will engage the uncut portion of the metal for the purpose set forth.

From the above description and disclosure of the drawings,

improved can opener it will be obvious that the includes many advan- I tageous features and by curving the body 2,

the same will coope to allow the knife to rate with the recess 14 be easily slid forward on 1 projection included in said tures.

its upstroke as it will be obvious that the recess will reduce the thickness of the blade and thereby the edges of the cut made by the blade will offer minimum resistance it any at the reduced portion.

It is thought from the foregoing description that the advantages and novel features of our invention will be readily apparent.

VJ e desire it tobe understood that We may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall Within the scope of the appended claim.

What. We claim is:'

A can opener of the character described comprising a blade, blade, guide means for said blade and in cluding a substantially U-shap'ed yoke havi ng one arm bent rearwardly upon itself, a guide means for engaging the outer Wall of a can and being formed with and depending from the rear- Wardly bent portion, means for pivotally securing said curved body to said guide means and passing through the other arm of the U-shaped yoke, a reduced portion depending from the guide.

member and being aligned with the projection for cooperation therewith, said blade being recessed ad acent its juncture with its body, said blade including a cutting edge and said edge being notched at its outer end. In testimony whereof We aflix our signa- HEDLEY FALLA. raED-nnRoAMr.
